A new 39″ x 39″ poster (or the size of an LP sleeve) shows the family tree of rock and all its connections with a handy dandy chart that shows exactly how 727 artists and 500 bands throughout music history are intertwined. You should kind of think about it as a Six Degrees of Kevin Bacon sort of thing.

The poster, made in Brooklyn, natch, includes a color-coded instrumental breakdown of what each musician played for each outfit. The company also promises that the poster includes fun facts for all the music buffs out there.
